There is absolutely nothing wrong with this at all...if EVERY league is going to be bowling on the same condition(s). And certainly no need for the league, or the house for that matter, to certify as Sport.
As has been argued time and again, USBC does NOT own the playing fields. Each playing field is owned and operated by an independent owner or corporation. None of those entities is required to do anything for USBC certification other than making sure its fields and conditions are LEGAL...that is all.
There is no rule stating that the condition at every house has to be the THS that most of us see routinely. Likewise, I would bet you that there are houses out there using conditions that are much tougher than the PBAX conditions...you know the "graveyard" houses. I have yet to hear of any league or house being rerated as Sport because it is a graveyard.
If you are so caught up because the lane condition has a name and marketing attached to it, simply ask the proprietor if he can remove/add a few units in the middle so that it is no longer the prescribed PBAX pattern.
Simply put, there is NOTHING that USBC can or would do about this. They haven't addressed the issue of "graveyards" v. "great wall of china." And there is no way for them to police such a situation anyway. Bottom line, USBC makes the rules...no rules are being broken.
